Description
Technical field
The present invention relates to technical field of aquaculture more particularly to a kind of inorganic agents for aquaculture pollutant.
Background technique
With being continuously increased for China's pond culture area, breeding wastewater is discharged and is formed by residual bait, excrement, biological remains
Organic sludge accumulation etc., it has also become the environment and ecological problem of public concern.The genotoxic potential of pond deposit dirt, inductivity
And biological accumulation effect will further deteriorate pond culture environment, cause fish morbidity to increase, the speed of growth is slack-off, quality of fish
Decline, seriously threatens the sustainable development of aquaculture.China pays much attention to the research of ecologic breeding in recent years, and successfully opens
Send out the technologies such as pond closed circulation cultivation, a variety of integrated cultures of Popularization And Development.But from general, pond culture is still
Lack system, practical healthy aquaculture mode, the processing of regulation and settled sludge to cultivating system inside water quality cannot reach
The requirement of safe and stable production, the self-pollution as caused by cultivating are still extremely serious.
Bait utilization is lower in the breeding process, and residual bait, aquaculture organism excrement etc. are the masters of culture environment of aquatic products pollution
Source is wanted, main pollution is organic polluted by nitrogen, causes the eutrophication of water body and C, N, P enrichment pollution of bed mud and bottom
Mud oxidation-reduction potential reduces.Therefore, the research of culture environment of aquatic products recovery technique has become urgent need.
Environment remediation technology has peripheral doses, chemical restoration and biological prosthetic.Physics, chemical repair method are mainly logical
Crossing the physical processes such as dredging, precipitating, filtering removal pollutant or application chemical reagent etc. makes polluter that certain chemistry occur
Variation, is converted into the engineering of innocuous substance, speed is fast but costly, and big a possibility that secondary pollution.Biology is repaired
Compound method be using microorganism, plant and other biological, by the risk contaminant degradation in environment be carbon dioxide and water or
It is converted into the engineering technology system of other innocuous substances, in-situ immobilization and showering can be divided into.Relative to other recovery techniques
For, biological prosthetic have many advantages, such as low-cost, and processing operation is simple and safety is higher, be a development potentiality compared with
Greatly, environmental-friendly processing technique.Bioremediation technology is applied in culture environment of aquatic products reparation, to recovery and optimization aquatic products
Breeding environment pushes the sustainable development of Chinese Fishery aquaculture to be of great significance.
Summary of the invention
It is an object of the present invention to be directed to the above-mentioned deficiency of the prior art, a kind of low-cost, processing operation letter is proposed

(2) it is put into syringe after microbial cells mixing is added after cooling；
(3) mixed liquor is slowly injected into the saturation boric acid solution of the calcium chloride containing 3%~6wt%, it is molten at this after adjusting pH value
Inorganic agent is crosslinked to obtain in liquid.Adjust the pH of the solution, it is ensured that bacterium keeps higher activity.
Above-mentioned is using using having very strong go to ammonia nitrogen in water body and nitrite nitrogen after embedding method imbedded microbe thallus
Except effect.Embedded immobilization is one of immobilized microorganism technology, with the method for physics by cell encapsulation gel net
It in network structure or is wrapped in semipermeable polymeric film, oxygen, the substrate of small molecule and product can freely enter and leave, and micro-
Biology is without leakage.
Preferably, the pH value is 6.5~7.
Preferably, 15~40h is crosslinked in the saturation boric acid solution of the calcium chloride containing 4wt%.
Polyacrylamide in inorganic agent for aquaculture pollutant of the invention is nontoxic, antidecomposition, plasticity are strong,
For sodium alginate as natural organic polysaccharide, permeability is preferable, but bad mechanical strength, and moisture content is high, prepares material and method to load
Body performance has a major impact, and microbial cells need it to be diffused into bacterial cell film surface by the duct of carrier degradation, pollutes
The degradation rate of object is influenced by carrier mass transfer rate.The transmittance process of solute occur mainly in surrounded by polymer chain it is aqueous
In microcell, any factor for reducing this space can all influence the diffusion of solute, add adsorbent in the carrier, load can be improved
The absorption property of body, the mixing embedding of a variety of strains for having Synergistic degradation function, reduces the accumulation of intermediate product, realizes organic matter
Permineralization.
